Marty Grohman
Marty is the youngest of 8 kids and grew up on a farm in Carthage, Maine, milking the cows before catching the school bus every day. Marty went to Dirigo schools and then to Gould Academy in Bethel as a day student, and then to RPI for engineering school. After graduating he got a job at GE Plastics, and worked all over the US and in Austria, helping start up plants making composite decking, and still holds some patents for the process.
Realizing that back home in Maine was the place he most wanted to be, but that there were not many jobs in Maine for chemical engineers at the time, he decided to start his own composite decking company. He settled on Biddeford as the best location, signing a lease in the Biddeford Industrial Park in 1999 and moving to the city. He grew the company, then known as CorrectDeck, to 75 employees in a 24/7 operation and made the Inc 500 list several times. Though he sold the company in 2009, it still operates in the Biddeford Industrial Park under the name Duralife Decking.
Marty served the city as a State Representative for two terms between 2014 and 2018. He was elected to the Biddeford City Council in 2021 and as Mayor in 2023 and served through 2025. While serving on the City Council, Grohman was a member of the Mayor’s Affordable Housing Task Force and the Climate Change Task Force. He previously chaired the Recycling and Waste Management Commission, helping to develop the City’s recycling program. He has also volunteered to revitalize West Brook Skating Rink and support local veterans. Marty and his wife Amy have been married since 2005 and they have two children.
